--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
Both crossjumping (on RTL) and tail-merging on GIMPLE perform the desired
transform inside a function. You are looking for the IPA side of this
(which only can common whole functions at the moment), basically function
part outlining plus ICF.
